What looks like its supposed to be some sort of Warehouse Log in Seyda Neen is instead named "??eò?aà? êíè?à". The inside of the book is written in a similar language. There are a few other books that have this same issue. Does anybody have a fix for this issue?

Have you downloaded Russian version by accident? Or maybe you're using Animated Morrowind Expanded, and that bug is from there?

I'm using the version included in MGSO which appears to be a compilation of Animated Morrowind, Animated Morrowind II, and Animated Morrowind expanded.
